2 Concrete Design Related Topics by CRSI... Dr. Mike Mota Economical Design and Detailing of Reinforced Concrete Structures (1.5 hr) This presentation provides information on how to economically design and detail conventionally reinforced concrete members that comply with the provisions of the 2014 edition of ACI 318, Building Code Requirements for Structural Concrete. Practical and timeproven methods and guidelines have been compiled from various sources to assist designers in the design and detailing processes of a reinforced concrete structure. Numerous details and design aids are provided that will help in achieving overall economy while reducing design/detailing time. Vibrations of Reinforced Concrete Systems (1.5 hr) This discussion presents detailed information on how to select an appropriate flat plate, flat plate voided concrete, two-way joist, and wide-module floor systems for various vibration acceptance criteria. The main topics are (1) sources of vibration, (2) vibration acceptance criteria, (3) vibration characteristics of reinforced concrete floor systems, and (4) selection process. Concrete Design Related Topics by ACI... Dr. Khaled Nahlawi Mass Concrete (1 hr) Mass concrete is defined as any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from hydration of the cement and attendant volume change to minimize cracking. But how does one predict whether mass concrete problems will occur and what steps should be taken? This presentation will discuss how to identify mass concrete, ACI 301 requirements pertaining to it, and good construction practices. Topics covered in this presentation will include: Examples of mass concrete structures How to identify mass concrete based on ACI s definition Factors influencing concrete temperature in mass concrete ACI 301 requirements for mass concrete Repair of Concrete Structures (1 hr) This presentation will introduce the ACI , Code Requirements for Assessment, Repair, and Rehabilitation of Concrete Buildings and Commentary. This is the first U.S. code produced specifically for the repair of reinforced concrete. A new guide document for the code with additional information and project examples that help users interpret the code requirements will also be highlighted. Topics covered in this presentation will include: Why a repair code is needed The philosophy behind ACI 562 How the code promotes consistency in repair design Recognizing repair construction challenges Significance of a quality assurance program for successful repairs How the code can save the owner money Lateral Framing Systems / Progressive Collapse / Mr. Jason Hoover: SidePlate (1 hr) Engineers will learn about conventional moment connections and problems that were exposed by the Northridge earthquake, as well as the resultant code changes in the years that followed. Attendees will also get an introduction to progressive collapse and PC mitigation concepts, how connection geometry and load transfer impacts overall frame performance, and how these framing selections impact the construction cost of the structure s lateral system. Serviceability for the Practicing Engineer / Ms. Emily Guglielmo: Martin and Martin (1 hr) Serviceability considerations are often subjective and historically building codes have been reluctant to impose clear serviceability criteria. However, serviceability issues are the primary cause of litigation in the construction industry. Structural engineers need to know how to design the buildings that not only withstand the code-required loads for strength limit states, but also meet a level of serviceability. This session will discuss specific code references for various material and systems, outline common industry practice procedures where codes are silent, and discuss the future of the codes as it relates to serviceability requirements. Lap Splices in Masonry Walls / Mr. Scott Walkowicz: Walkowicz Consulting Engineers (1 hr) U of M Biological Sciences Building / Ms. Andrea Reynolds: Smith Group JJR (1 hr)

3 Jeddah Tower Rising / Mr. Matt Huizinga: Thornton -Tomesetti (1 hr) Construction of the meter tall Kingdom Tower in Jeddah, Kingdom of Saudi Arabia is currently well underway with all tower piling and raft foundation complete and superstructure concrete reaching 200 meters in height. The lecture will focus on the significant technical engineering challenges of designing the next world s tallest building. A brief overview of the architectural and master planning scheme for the tower and the surrounding developments is presented as an introduction to this unique, groundbreaking project. Important aspects of the geotechnical site exploration program, piled raft foundation design and significant foundation-tower interaction studies are presented; along with long term settlement predictions, the completed pile load testing program, and ground seismicity studies. The superstructure frame is composed almost entirely of reinforced concrete walls and coupling beams. The structural system was developed based on the need for simplicity and repetition during the construction process. The concrete bearing wall system chosen is unique for ultratall tower schemes in that it relies on no outriggers or belt walls, no column transfers, very little differential shortening in vertical elements, and only 85 MPa concrete strength. The presentation will focus on the development of the tower structural system including historical precedents, the wind tunnel testing program and other unique aspects of the tower structural engineering design and construction planning. Particularly critical technical issues such as the prediction of vertical shortening due to the long-term creep and shrinkage of the concrete frame, and behavioral characteristics of the tower under lateral and gravity loadings are also highlighted. The project is scheduled for completion in late Exhibitors: Lincoln Room All day long: particularly at breaks & lunch
